Damn, same thing happened to me.
Did the doctors say if you would end up with a "claw" from losing motion and sensation in those 2 fingers?
Take the physical therapy slow n steady cuz it helped me get my movement back at least. The sensation is weird, like I can feel things but I can't with those two fingers.
The 2 fingers are already forming a claw, 2 weeks out of the hospital now. I wasn't prescribed any real physiotherapy or anything.
I just take vitamin b12 to improve nerve function and use a stress ball to grip during the day. Haven't noticed any improvement so far though.
The 2 fingers move a tiny bit in coordination with my other 3 fingers but I can't use them individually at all. The sensation is really weird too, feeling things with only 3 fingers. I don't have any nerve function in my left knee either from a previous surgery but it doesn't bother me at all, whereas this feels really uncomfortable.
